Abstract: Pie´ron's law, which formulates the effect of the signal intensity i on the mean or the median reaction time (MRT) as a power function, MRT ¼ R þ i Àb C; in which R, b and C are positive parameters, is of much interest in the simple reaction time literature. In particular, consistent estimates of b are obtained. However, this law offers no information regarding the effect of the signal intensity on other aspects of the reaction time distribution. In addition, the background intensity, which also has some impa…
